Ensure the analog device is correctly connected to the FXS port with an RJ11 cable. Verify the FXS port is enabled and configured correctly in the device's web interface. Check that the SIP account is registered.

Check your internet connection speed and stability. Ensure QoS settings are properly configured on your router and the HT814 v2. Try selecting a different, less bandwidth-intensive voice codec.

Double-check the SIP server address, username, and password in the configuration. Ensure your firewall is not blocking SIP traffic (ports typically used are 5060/5061). Verify the device has a stable internet connection.
